Description of EVA Film:

 

EVA film is based on EVA resin which basis to ethylene and vinyl acetate copolymer resin, by adding a variety of modified additives, through melt extrusion made of the rmosetting hot melt film. Not be sticky in normal temperature, easy to operation. Produced by thermal lamination with the bonding enhanced crosslinking chemical reactions, making silicon wafers, glass, TPT multilayer material consisting of one firm bond as the product of solar panels, in actual outdoor applications up to 25 years life. A large number of applications at home and abroad well-proven solar panels, EVA film is the optimum cost performance, it is difficult to alternative packaging materials for solar cells.

Q:Early spring seedlings using light blue plastic film or white plastic film?
Use blue film. Because the early growth and development of crops are in a weak period, the impact on the environment is great.
Q:What are the composite ways of plastic film?
Extrusion (casting, lamination) composite method refers to the PE or PP material after hot melt film extrusion, namely resin melting, extrusion pour in the plastic film, paper, aluminum foil, metal rolling drum vacuum aluminum plating film, the processing technology of the compound pressure after cooling. The composite product formed by pressing on the printing film is characterized by low cost and reduced glue pollution. But it is better to choose the type of extrusion material and control the extrusion temperature. In addition, a small amount of base rubber or AC agent is used as a coupling agent in the film. Extrusion (casting, lamination) composite method suitable for large quantities of varieties, but the film is not composite after (film above 0.05mm).
Q:What is a water-soluble plastic packing film?
Water soluble plastic packaging film as a new green packaging materials. The main raw material is low alcoholysis of polyvinyl alcohol film, water solubility and degradability by polyvinyl alcohol, adding various additives, such as surfactants, plasticizers, anti adhesive agent. Water soluble film products belong to green packaging materials and in Europe, Japan and other countries have been recognized by the national environmental protection department. At present, the main domestic and foreign biological oxygen demand (BOD) and chemical oxygen demand (COD) as an environmental indicator. The Japanese authorities determination of PVA biological oxygen demand (BOD) is much smaller than the starch, the United States Air Products to PVA biological products Airvol, after 5 days degradation can be measured the amount of BOD is lower than the initial volume of BOD 1%. through the biological experiment proved that polyvinyl alcohol are non-toxic, does not prevent the growth of microorganisms, has no influence on wastewater treatment and environmental health The microbial decomposition tests also showed that the PVA was almost completely decomposed, resulting in a very low COD
Q:Do I need to tear the plastic film of the barrel washing machine?
Just like this, generally this began to use, and then removed, at home for after, generally will not move, and damage the shell, the opportunity is much less, it does not matter whether it is necessary to protect the film.
Q:How to remove the plastic film on the steel door?
If it is an old door, it is best to use a blower to blow it aside and tear it away.
Q:What is the corona treatment of plastic film?
In the corona discharge, a large amount of ozone is produced. Ozone is a strong oxidant which oxidizes the surface molecules of plastics and produces carbonyl compounds, peroxy compounds, and so on. In addition, corona treatment to remove oil, dirt and moisture and other effects, through the modification of the physical and chemical, can significantly improve the plastic surface wettability and adhesion.
Q:Does the plastic film on the bank card fall off and affect the use?
The damage of the plastic film on the front of the bank card does not affect the use of the card. The key is the magnetic stripe on the back of the bank card. If the magnetic stripe is valid, your bank card can be used normally. It doesn't matter.
Q:Can plastic film protect against ultraviolet rays?
The transparent film itself UV blocking effect is not good, the general need to add other ingredients, such as color masterbatch, metal particles etc.
Q:What color glass, plastic film or supplementary light source should be chosen for growing vegetables in greenhouse?
Hello friends, plastic greenhouse planting eggplant fruit vegetables suitable plastic film is EVA film, PO membrane two kinds, PO membrane price is too high, and use the most common or EVA film.EVA film transmittance, high temperature, fast, good insulation, the price is suitable for every square in a piece of five to two blocks between.Others, such as poly vinyl non dripping film, this is to filter UV, affecting the coloring of vegetables. Grouting film is cheap, the disadvantage is that the temperature is too fast, low transmittance, no drop is too short.
Q:FFS plastic film bags are injection type?
FFS plastic film bags are not injection molding, blow molding. The continuous production of "forming filling sealing (Form Fill-Seal, referred to as FFS)" bag blown film products, is a domestic heavy packaging film technology developed in recent years, mainly used for automatic packaging line of large polyethylene, polypropylene and other synthetic resin products.
PROTECT, is the professional manufacture Enterprise with the largest investment scope, the most comprehensive product Specifications, strong production capacity and the highest sales volume, mainly produce special materials PVB and EVA film for bullet-proof glass, windscreen of the automotive, architectural safety glass as well as solar cell panel.
